t No. 533.

To `all wiomz't may cof/teem Be it known that LISAAO CRossETT, of EastiBenningtomin the county of Benning; ton and` State ofVermont,have inventedta `new and useful Seriesof Machinery for the Manufacture of Barrels and other Casks, wliereofthe following is a full,clear, and exact description ofA theY construction and operation of the same, reference b-eing had:

t-o the annexed` drawings, making part of this specification-that is to say,

`lst, an improved machine,Figure l, for cutting heading from steamed blocks ofsuit` able wood, which improvement consists in a knife or cutter lV, aiiixed" to a lever 13,1),

movable about the point B as aA center, the

cutter attacheolto saidlever byscrews which enable the operator to set tlieedge ofthe knife to suit the grainofthe wo-od and to cut the heading of any required thickness,`

and which saidlever itself serves as agage to` regulate the thickness of the "stuff, and

a cutting block or bed piecev A, a, movable about the point A as a center.

These two parts are put in` motion` by two connecting rods ci, (l, and 11,6, attachedto a vibratory farther from the line of the cutting edge.

A modification of this machine, as seen Fig. 2, where two bent or elbow levers moving in opposite directions and in a suitable curve,

one carrying a curved knife, and the other a bed piece, may be used for listing staves.

2nd, a stave cutter Fig. 3. D is a knife or cutter, which is firmly iixed by its extremities to two uprights, by means of screws which also serve to regulate the knife by setting its edge in or out. E is agage for the thickness of the staves, and is likewise fixed t0 the two uprights by screws in such manner as will allow of its being moved to regulate the thickness ofthe staves; F is a cutting block or bed piece, on which the block of steamed wood is placed and held, this bed piece receives a vibratory motion about its fulcra f, f, by means of two levers g, g, at its extremities, moved by the connecting rods s, s, `or by any othermeans which will give the required motion; the ob- Vject being to carry the block to bre cut against the stationary knife, in ali arc of a circle whose radius is equal to that ofthe cask to be constructed by means of a vibrating Vbed which enables the operator to push the `block downward, toward the gage when the machine isready to cut, and to draw it downward from the knife, after the cut, either to` turn the block, as isifrequently necessary or to withdraw the; coreafterthe block is cut, The` knife or cutter is formed of the lower portion of a crescent, whose inner circle is concentric with the axis of rotation of the bed piece. The fulcra` of this bed piece can be made to regulate so as to cut, staves `to different radii.

3d, a stave jointer, Fig. d, consisting of two circular saws revolving in two planes so inclined to each other as that their line of intersection is a little below the centerline of the `cask to be constructed, by which means the inside `of the joint willbe a little full.

One end of the stave to be jointed is placed under the notch `taand the other is sprung` down over the saddle j on the carriage G (as seen in detail on 2nd sheet of dra-wings, and held down by lock Z, being thus held the stave, on the carriage,is pushed throughbetween the saws, which joint it oit, giving the proper taper and bevel tc form a perfect joint; when the carriage is pushed through so far as to bring the pin in contact with the stop 7e, and thus relieve the lock Z, thespring of the stave throws the lock back; at the same moment the pin p, in the carriage strikes the short arni r of the Cleaver, causing the long arm t to strike against the stave and knock it clear of the machine, when the carriage is drawn back to receive another stave.

4th, an improvement in the working oif machine, which consists in a swiftly revolving disk L, Fig. 5, on the face of which, and at proper distances from the center are placed the leveler i, and chamfering tool e. On the face ofthe wheel is also placed the croze n which is fixed in a groove, or held by hooks as seen in detail on second sheet, so that it can slide freely in a plane perpendicular to the axis of rotation. The cask N, set up and trussed, is placed in a carriage or clamp with its axis exactly corresponding with that of the revolving disk, and to be advanced toward the latter until the chainfer and leveler `have done their work, and the end of the cask is entered into the countersink in the disk, which will prevent it from shaking; then seizing the handle K, and causing the small wheel to advance on its axis toward the large one, 0the small wheel will press upon the bent lever c and drive the eroze out to do its work, then letting go the handle, the spring x throws the cro'ze n back, so that the Cask can be withdrawn and turned around to work the other end, or exchanged for another to be worked off in like manner.

5th, ya head machine, Fig. 6, which consists of a wheel M revolving swiftly on its horizontal axis, carrying on its periphery one or more segments of a band saw 7i, z., the teeth of which project a little over the face of the wheel. On the disk of the wheel, and at its edge are placed other segments w, w, of flat saws (or knives) between and at right angles wit-h the first, and extending also a little beyond the exterior circumference of the wheel. The pieces to form the head are placed between two disks `0, 0, and Q, Q, whose common axis is in the same vertical plane with the axis of the first wheeland inclined thereto at an angle of about degrees; the axes of these two disks are supported upon a carriage H H H. The upper disk is movable in the direction of its axis, and the lower one is set with a great number of metallic points or spurs; when the pieces to form a head are placed on the lower disk, the upper one is brought down, pressed hard and firmly held by means of the two levers m, m. The carriage H, H, is then pushed up so as to bring the lever part of the heading in Contact with the lower edge of the revolving disk, when t-he saws will cut through the heading at an angle of about 45 degrees on the upper and 45 degrees on the lower face, forming a right angle on its edge; and if the proportion of the two disks be such that the arc of the circle on the lower edge of the vertical disk coincides perfectly witli'the segment of the ellipsis projected from the inclined one, the incision will be the are of acircle, then seizing the handles w, e, and causing the head to revolve once on its axis it will be fitted to enter into the crozing; the carriage is then drawn back,

the levers raised, the head taken out, other pieces put in and the operation repeated.

Now, what I claim as my invention, and

wish to secure by Letters Patent isel. In the heading cut-ter, attaching the knife Y and bed each to a lever, so arranged as to cause the knife and bed to move in opposite directions by means of which arrangement more or less draw can be given to the cutter as herein before described.

2. YIn the stave cutter, the vibratory motion given to' the bed piece, by which means the labor of feeding the `machine is greatly facilitated,inasmuch as the bed is inclined downward toward the gage when it is readyk to cut (which makes it feed easily), and

from the knife after the cut, so that the hot Y [Fiicsr PRINTED 1913.]
